Patented June 3, 1930 UNITED STATES DANIEL IVL AUVIL, F RYDERWOOD, WASHINGTON SAW-SUPPORTING DEVICE Application filed March 28, 1928. Serial No. 265,258.

This invention relates to improvements in saw supporting devices and more particularly to devices of that character used for undercutting; the principal object of this invention being to provide a'device that may be used in combination with an axe after the latter has been sunk into a log and which is readily adjustable and will serve satisfactorily as a guide and support for a saw used in undercutting the log.

More specifically stated, the object of the invention resides in the provision of a device for the above purpose comprising a supporting plate that is adapted to be applied to an axe head, with an arm pivotally and adjustably attached to the support and equipped with a roller on which the saw may be func tionally supported in operation.

Other objects of the invention reside in the various details of construction and combination of parts as hereinafter described which provide for attaching the device to an axe and for adjusting and retaining the arm at various positions.

In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of a saw supporting device constructed in accordance with the present invention, showing it functionally applied to an axe head.

' Figure 2 is an end view of the device illustrating its use as a saw support and guide.

Figure 3 is a sectional detail showing the means for attaching the device to the axe head.

Figure 4 is a face view of the axe head. showing the relation of the holes provided for attaching the hanger thereto.

Referring more in detail to the drawings- The present device is used as an attachment for an axe and in use is applied to the axe head after the latter has been sunk into the log which is to be undercut; the log being in a horizontal position, the axe head is stuck into it so that a flat side faces upwardly, as shown in Figure 2.

In its preferred form, the attachment device comprises a hanger plate or bracket 1 adapted to be disposed against the outer edge of the axe head designated at 2 and is pro vlded at its upper end with a laterally turned flange 3 adapted to overlie the upper flat surface of the axe. This flange has two spaced studs 4 fixed therein adjacent its opposite edges adapted to project downwardly and into sockets or holes 5 provided in the upper face of the axe head to receive them. It is preferred to provide the axe head with three of these holes with the centrally located hole set back from the edge of theaxe farther than the outer, or end, holes so as to provide for holding the hanger in different angular'positions with respect to the head, as is illustrated in Figure 4:, as a means of better accommodating right or lefthand'cutting. The studs 4 are of such length as to retain the hanger securely attached, or, if necessary, they may be replaced by bolts that are threaded into the socket or holes in the axe head to more securely hold it.

' The hanger plate or bracket 1, as ordinarily made, is from six to eight inches long and at its lower end is provided with a continuing arm 8. This arm is pivotally attached at one end to the hanger by a pivot 9 and is adapted to swing in a plane parallel to the plane of the arm. Atits swinging end the arm is equipped with a grooved roller 10 on which a saw, as designated at 11, may be supported for use in undercutting the log into which the axe head is struck.

The arm is adapted to be swung in opposite directions to best accommodate the saw, and it may be held at different positions by means of alink 12 that is pivotally attached at one end to the arm and at its other end has an inturned hook 14 adapted to be applied to any of a plurality of holes 15 arranged along the hanger plate 1; it being apparent that it will be desirable to raise the saw as the cut is advanced upwardly through the log.

Assuming the device to be so constructed,

it is used as follows: First, the axe head is struck into the log, as shown in Figure 2, then the studs 4 in the laterally turned flange 3 of the hanger 1 are applied to the holes 5 so that the hanger depends downwardly; the

angle of the hanger with respect to the axe being determined by the pair of holes that are selected. The saw supporting arm is then adjusted to proper position and held by the link 12 and the saw placed for travel on the roller 10. It is apparent then that the saw may be reciprocated to undercut the log and that the arm may be re-adjusted so that the roller will be in a position to serve as a support until the limit of the arm has been reached; then, it necessary, a re-setting of the axe may be made.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent, is:

1. The combination with an axe or the like,-

of a saw support comprising a hanger plate havingv'a laterally turned flange at its upper end adapted for attachment to the axe, an arm pivotally attached to the lower end of the hanger to swing in a plane parallel with the plane of the hanger, a link connecting the arm and hanger to support the arm at various positions of adjustment and a saw supporting roller at the end of the arm.

2. The combination with an axe head having a plurality of holes provided in a face thereof; of a saw supporting device comprisingav hanger plate provided with a row of holes'in spaced relation and provided at its upper end with a laterally turned portion having studs projected downwardly therefrom adapted to seat within holes in the axe head, an arm pivotally attached to the lower end of the hanger to swing in a plane parallel with the plane of the hanger, a link having an end ,p ivotally connected with the arm and its other end provided with a hook adapted to be applied to any one ofthe holes of the hanger as am-eans of supporting the arm at different positionsof adjustment and a saw supporting roller at the end of the arm.
